I really enjoyed the bike tour. Before heading out to Karlstejn we rode around old town Prague. The ride along the river was really nice. Mostly flat and easy with a few easy hills. A very nice way to see the countryside. We stopped mid way for a beer break which was a nice treat. The guide was a nice young guy originally from Ukraine. I forgot his name but he was a real nice and knowledgeable guy and the info he shared about of the area was very interesting. If I get to return to Prague, I'll definitely join this bike tour company again.

This was the highlight to our visit to Prague! Sasha was our bike guide, and he was friendly, knowledgable, and really helpful. The bikes were in great condition, with really good gears. The bike ride was beautiful! And the train ride back was a fun way to end the tour. I would do this again.

Our guide was fantastic, very informative about history and local sites. The bike ride was beautiful, and well worth the time to experience the countryside outside of Prague. I would say that you should know that the route is not as flat as described. It can be a little challenging to ride on cobblestone streets and through some areas of heavy morning traffic in Prague, and there are inclines along the route that would be difficult for inexperienced riders. People with bad knees, like myself, may find the hilly parts of the ride challenging and the pace too fast. Our guide did adjust the pace when needed however. Overall it was a great experience which I would be willing to do again. My husband did not find the ride challenging, but he is very used to hill riding and road racing.

Great tour. Was a long and hot day, but our time was not diminished by uncooperative weather! Daniel was an excellent guide and made this trip so much fun. Lunch was good and Karlstejn Castle was beautiful!

18 miles is a lot of biking when you're not used to it, be aware that you will probably be saddle sore for a few days afterward. That being said, biking through the countryside was beautiful. Our guide, Travis, was quite knowledgable about Czech history and culture. There were only a couple of big hills to deal with, the majority of the ride was fairly flat. The tour price does not include entrance to the interior of the castle. You can get into the exterior courtyard and look around the outside but a tour of the interior is an extra cost and the tour is conducted once an hour. We chose not to do the interior tour. The train ride back to town was quick and easy. All in all this was an excellent tour and was the highlight of our Prague vacation.

This trip was an absolute 5 star perfect day for all (2 parents, 2 kids age 15 and 17).

Easy to find the start location. Bikes were selected for our height...and the bikes were of good quality. Brief fitting of saddle height. Then a short ride thru Prague to test the fit and a short tour of several local buildings. Then we set off along the Vltava.

The route is flat and very scenic. 32 km in distance. We stopped periodically to regroup and 1 20 minute stop for refreshments about halfway I had a beer.

At Karlstejn we had a fabulous lunch and then the castle tour which was excellent.

Then a 5 minute ride to the train station in Karlstejn, and a 45 minute train ride back to Prague. Then 5 or 10 minutes more cycling back to the start location.

This was a perfect tour, especially made possible by our exceptional tour guide, Sasha!
Would highly recommend it to others looking for a different way to see and learn about
Prague and it's surroundings than a typical bus tour. Would not have changed a thing...

This tour was a great escape from the city. Our tour guide was Nick and he was really knowledgeable about Czech history and customs. I don't think there was a question that he could not answer! If you want to see a different side of the Czech Republic and a pretty cool castle stuck in the middle of some mountains, I would definitely recommend it! Make sure you're ready for a good amount of biking!

The tour was great and we loved our guide, Nazar. I would recommend the tour for active people though. There were quite a few hills and the walk to the castle itself is quite strenuous. The castle and surrounding village are both beautiful. It was neat to see the countryside on the ride there.

Great way to spend some time out of the busy city and see another side of the Czech Republic. The ride was an easy ride although it is very tiring. The restaurant stop was perfect for local Czech cuisine and the tour guide was very easy going. He made sure the equipment was ok and stopped several times to make sure all guests were doing well. The price does not include the tour of the Castle so be prepared to pay additional for a tour of the castle.
